A tooling jig is described for accurately cutting planar material, such as laminate faced chipboard. A base board has a guide fence extending therealong which has a straight edge against which one edge of the workpiece is clamped. A bridge is secured to the base to overlie the workpiece and the bridge has a guideway thereon extending accurately perpendicular to the straight edge, the guideway being adapted to allow for movement therealong a router. The router will finish accurately a workpiece which has been cut slightly overlength, the edge machined by the router being accurately perpendicular both to the edge against the guide fence and to the faces of the chipboard.
